11 Claims.

The invention relates to improvements in sandwith a valved nozzle whichis adapted to automatically open to supply sand when the nozzle isplaced in the opening in the wall of a sand box on a locomotive and isadapted to automatically close as soon as the nozzle is removed from thesand box, thus avoiding wastage and loss of sand.

Another feature of the invention resides in the use of a sealing platein'connection with the sanding hose which is adapted to seal the openingin the sand box when the vhose is positioned therein.

Another feature of the invention resides in the provision of means forsupporting the iiexible hose pipe in such a manner as to prevent sag ofthe pipe below a slope whichV insures a satisfactory ow of sand.

Another feature resides the improved gate valve mechanism associatedwith the sanding nozzle.

`While the present device has been particularly designed for use inconnection with sanding hose and nozzles intended for servicinglocomotives, it will be understood that the invention is of wideapplication and in its broadest aspect is not confined to thisparticular use.

The invention will be more readily understood by reference to theaccompanying drawings and the following detailed description, in whichis set forth by way of illustration a specific embodiment of theinvention.

Fig. 1 isa view inelevation with parts in section of the sandingapparatus, dotted lines showing different positions of the hose andnozzle, and a portion of a locomotive wheel upon a track beingdiagrammatically shown also in dotted lines;

Fig. 2 is a detail section on line 2-2 of Fig. 1 but on a larger scaleshowing the rotatable attachment of the hose and the sand supply pipe;

Fig. 3 is a sectional view on a larger scale than Fig. 1 of the nozzleapplied to a sand box opening, the nozzle valve being shown in openposition;

Fig. 4 is a front view of the nozzle showing the sealing plate in fulllines and the slide plate in dotted lines;

Fig. 5 is a section on line 5 5 of Fig. 3; and

Fig. 6 is a View similar to Fig. 3 with parts in elevation but showingthe nozzle removed from the sand box opening and the valve closed.

Referring to the drawings, A represents a flexible hose pipe forsupplying sand to the sand box of a locomotive. The pipe may be of anysuitable material and, as shown,- is connected at its upper end by aswivel joint B to a sandsupL ply pipe C supported on an upright post D.By reason of the swivel connection B a single hose pipe may be used toservice locomotives standing on two adjacent tracks. t

Adjustably carried by the upright D is a clamp E to which is connectedone end of a hose supporting rod Fl` provided with a clamp Gr at itsother end adapted to slidably engage the hose A intermediate its ends.As Figo'. 1 indicatesrthe supporting rod F will support thehose when inuse at such an angle that sag is eliminated and free flow of sand to thesanding box is insured.

At the lower end of the hose A there is provided a two-part valvednozzle H, which is the subject of the present invention. and which isadapted to be inserted within opening in a locomotive sand boxdiagrammatially indicated at I. The, nozzle is of Such construction thatas. Soon as its end is inserted. in the Sand box opening and rests uponthe portion of the Sand box wall beneath the opening, the nozzle valvewill be automatically opened to at once supply sand to the sand box, butas soon as the .nozzle is removed frorn the opening the valve will beautomatically closed, thereby preventing wastage of sand. Suitablesealing means may be provided in conneotion with the nozzle so that atight t may be insured between the sand box `opening and the nozzle.

As shown, tne nozzle H consists of two tubular parts I0` and II, Withautomatically operating valve means connecting the two parts. The upperpart IIJ is connected to the hose pipe A by means of a suitable clampI2. The lower part I l is adapted to be inserted in the opening in thesand box I with its under surface resting on the portion of the sand boxwall beneath the opening. l

As shown, the lower nozzle member II is provided with a sealing plate I3which may be secured to the member Il by any Suitable moans. as bywelding or brazing, at I The plane of the sealing plate I3 is preferablyat an oblique angle to the central axis of the nozzle portion II towhich it is secured, and theplate I3 is pro-` vided with an opening l5in alignment with the bore of the nozzle member Il. Thus, the plato I3serves to seal the opening in the sandbox when the nozzle member isinserted therein, :and `also provides a limiting stop for the` nozzlel'twill be apparent that the sealing action is aided by the diagonalmounting of the sealing plate. If a tight joint is desired suitablepacking means may be provided at the surface of the sealing plate. Suchpacking means. would render the nozzle iluid tight-so that it could beused for supplying liquid as Vwell as fluent materials such as sandandthe like, for which it is primarily designed.

` The sealing plate I3, together with its opening I5, comprises onemember of the automatic valve with which the nozzle H is equipped, theother member comprising a slide plate I6 carried by the upper nozzlemember Ill and slidably connected to the sealing plate I3 by anysuitable means. As shown, the plates I3 and i6 are maintained inabutting sliding relation by means of guide ilanges I'I carried by thesealing plate I 3. Upward movement of the slide I6 with reference to thesealing plate I3 is limited by a top flange I3 on the sealing plate I3,-and similarly, downward movement of the slide plate is limited by a pairof stops or screws I S, I9 carried by the sealing plate.v The slideplate I6 is provided with an opening 20 which permits passage from theupper portion of the nozzle into the lower portion thereof when theopenings 20 and I5 in the plates I5 and I3, respectively, are broughtinto registry. In accordance with my invention this occurs when thelower nozzle member II is inserted through the opening in the sand boxand rests upon the wall portion or ledge below said opening, the weightof the upper nozzle member I I! and the parts rigid therewith causingthe slide member I6 to move by gravity to its lowest position limited bythe stops I9. The sand may then be allowed to ilow through the nozzlewithout fear of overow, as when the box is full the sand will pile up infront of the nozzle opening and prevent further flow, thus providing anautomatic cut-off which requires no attention from the operator.

When the nozzle H is removed from the opening on the sand box the weightof the outlet nozzle member II and the sealing plate I3 connectedthereto causes the sealing plate to move downwardly with reference tothe slide plate until the upper end of the slide plate contacts theflange I8 at the upper edge of the sealing plate, in which position theopenings I and Z8 are out of registry and further flow of sand throughthe nozzle H is automatically cut off.

If desired a pivoted, automatically operating member 25 may be providedto latch the valve in both open and closed position, the latch being'held in lock by gravity. It will be seen from the drawings showing theopenings in open position (Figs. 3 and 4) that due to the design ofthese openings when the outlet member I I slides downward relative tothe inlet member I il to close the opening a minimum of sand grit can bedrawn into the contacting faces near the lower half of the opening andnone in the upper half, and when said outlet member slides upwardrelative to the inlet member to open this opening a minimum of sand gritcan be drawn into the contacting faces near either the lower or upperhalf of the opening due in part to the design and in part to thecontinued outflow in the outlet end until closure is complete.

From the above description the desirability of a vertical slidingmovement of the two valve members with reference to each other will beapparent, the outlet member II moving upward tolopen the valve, anddownward to close the va ve.

The invention has been described in dtail f01` 4 the purpose ofillustration, but it will be obvious that numerous modiiications andvariations may be resorted to without departing from the spirit of theinvention.
